Functor Command

Defined in System.FTDI.MPSSE

Methods

fmap :: (a -> b) -> Command a -> Command b

(<$) :: a -> Command b -> Command a

Applicative Command

Defined in System.FTDI.MPSSE

Methods

pure :: a -> Command a

(<*>) :: Command (a -> b) -> Command a -> Command b

liftA2 :: (a -> b -> c) -> Command a -> Command b -> Command c

(*>) :: Command a -> Command b -> Command b

(<*) :: Command a -> Command b -> Command a

run :: forall a. InterfaceHandle -> Command a -> IO (Either Failure a)

Assumes that the interface has already been placed in BitMode_MPSSE using setBitMode.

data Failure

Constructors

WriteTimedOut ByteString Int

content to be written and number of bytes actually written.

ReadTimedOut ByteString Int ByteString

data written, expected returned bytes, and data actually read.

ReadTooLong Int ByteString

bytes expected and content actually read.

BadStatus ByteString

Instances

Show Failure

Defined in System.FTDI.MPSSE

Methods

showsPrec :: Int -> Failure -> ShowS

show :: Failure -> String

showList :: [Failure] -> ShowS

Clock divisor

setClockDivisor :: Word16 -> Command ()

FT232H divide-by-5

enableClkDivBy5 :: Command ()

Enable clock divide by 5 to allow for backward compatibility with FT2232D.

disableClkDivBy5 :: Command ()

The FT232H, FT2232H, and FT4232H can achieve higher data rates if the clock divider is disabled.

enable3PhaseClocking :: Command ()

Enables 3 phase data clocking. Used by I2C interfaces to allow data on both clock edges.

disable3PhaseClocking :: Command ()

Disables 3 phase data clocking.

Loopback

enableLoopback :: Command ()

disableLoopback :: Command ()
